[0036] Working principle: During the use of the filter valve body 1, when the filter valve body 1 is in contact with the surrounding environment or subjected to external force, the wear-resistant layer 201 can withstand friction and impact, protecting the filter valve body 1 from being worn and damaged. During installation or transportation, the filter valve body 1 may collide with other objects, and the wear-resistant layer 201 can play a buffering and protective role. When the water flow passes through the filter valve body 1, the filter screen 202 will preliminarily filter the water flow, intercepting larger particles of impurities such as sand, rust, etc. After the water flow enters the filter valve body 1, it first passes through the filter screen 202, and larger particles of impurities are blocked by the filter screen 202, while the relatively clean water flow continues to flow to the subsequent filter structure 6. The first connecting pipe 401 serves as a part of the universal valve body 5 connected to the external pipeline, and the second connecting pipe 402 is used for the connection between the filter valve body 1 and the external pipeline. The bearing 403 enables the universal valve body 5 to rotate the filter valve body 1.

The two wear-resistant pads 406 reduce the wear of the connection part and improve the stability and durability of the connection. When the water flow passes through the filter valve body 1 and the universal valve body 5, the connection rotating structure 4 ensures smooth passage of the water flow. At the same time, due to the presence of the bearing 403, the universal valve body 5 can be rotated as needed to adapt to different installation environments and water flow direction requirements. The first and second sealing gaskets 404 ensure that the connection does not leak, ensuring the normal operation of the filtration system. The wear-resistant pads 406 can reduce the wear of the connection part during use, prolonging the service life of the connection rotating structure 4.

[0038] When the water flow passes through the universal valve body 5, the stainless steel mesh 601 serves as the outermost layer of the filter structure 6 and mainly plays a preliminary filtering role, intercepting larger particles of impurities such as rust, sand, etc. The glass fiber 602 has a fine fiber structure that can further filter small particles and suspended matter in the water. The activated carbon 603 has strong adsorption capacity and can adsorb harmful substances such as odors, organic matter, and residual chlorine in the water.
